Several stories in the COP27 Anthology showed how biochar works as a climate solution, in particular Mangrove Maj. Biochar is charcoal made from plants that helps bring back life to degraded soil. There are already a number of small operations working with this solution around the world such as Renewables Plus, Pyreg and Puro.
Our experts have classed this solution as a ‘low hanging fruit’ (relatively low cost and quick win).
How does this solution rate on:
|Climate impact: tonnes of carbon saved/removed||Sites can produce between 1 tonne per year and 10,000 tonnes per year of biochar = 3 tonnes of CO2 sequestered.|
|Climate adaptation-resilience||Biochar in the soil helps rebuild soil health and water retention.|
|Social justice i.e. addresses inequalities, diversity, inclusion||Integration of carbon credits into the agricultural process provides additional sources of revenue for rural people and businesses.|
|Cost of action needed to progress goal||Various types of equipment are available which can be used by low-cost small-scale operators and high throughout large-scale operations.|
|Which location is the solution most needed/applicable||The process can be most effectively deployed on plantations and industrial sites that are already handling large quantities of biomass.|
|Risk||As the process is distributed across the land, it is low risk.|
|Feasibility||This process could be widely applied today.|
Do your own research on the solution
This short video explains how a company called HUSK use biochar in Cambodia to fight the climate crisis.
These two TED talks also give a good explanation of biochar and how it works:
This BBC Horizon documentary also illustrates the history of biochar. The solution is not a new one that we are proposing. In fact, it was already used by the inhabitants of the Amazon Rainforest pre-Columbus. Whilst the solution is easy, cheap and effective, biochar is yet to become a mainstream solution.

Here are a series of steps you can take to progress this climate solution further. You can also contact us at email@example.com and we’d be happy to connect you with experts in these solutions to discuss further.
|Actions for policymakers||Biochar is a straightforward climate solution that is small scale now and could be much larger.|
Carbon credits should be graded so that the highest quality credits such as those from biochar are clearly differentiated from others. Offsetting activities should include a % of these high-grade credits, and a sliding scale of the lower-grade alternatives.
Soil restoration should be prioritised. The registration of projects for carbon credits is onerous. It is not worth developing a project of fewer than 1000 tonnes. This should be greatly simplified. To balance this inconvenience, it should be made more inconvenient to run a CO2 emission source.
For example, all vehicles, machines or generators with a fuel tank of more than 70 litres should be registered as a large emissions source – this includes most big SUVs and pickups. An onerous form, matching that of a carbon credit registration, should be filled in, detailing the operation of the CO2 source, so that a better understanding of these sources can be generated, and to discourage non-essential use.
|Actions for funding bodies||Provide full funding for dozens of projects in multiple locations around the world.|
|Actions for business||Use as many high-grade carbon credits as possible. Be prepared to pay in advance for better credits. Work with agricultural suppliers to help them convert their agricultural residues into biochar.|
|Actions for public||Reduce personal consumption of all things, and offset high carbon activities such as flying.|
